Usage
When you enable wred ecn, and the number of packets in the queue is below the
Information
minimum threshold, packets are transmitted per the usual WRED treatment.
When you enable wred ecn, and the number of packets in the queue is between
the minimum threshold and the maximum threshold, one of the following three
scenarios can occur:
•
•
When you enable wred ecn, and the number of packets in the queue is above the
maximum threshold, packets are dropped based on the drop probability. This
behavior is the identical treatment a packet receives when WRED is enabled
without ECN configured on the router.

If the transmission endpoints are ECN-capable and traffic is congested, and the
WRED algorithm determines that the packet should have been dropped based
on the drop probability, the packet is transmitted and marked so the routers
know the system is congested and can slow transmission rates.
If neither endpoint is ECN-capable, the packet may be dropped based on the
WRED drop probability. This behavior is the identical treatment that a packet
receives when WRED is enabled without ECN configured on the router.
— creates a WRED profile and name that profile.
